ISU is a robot able to write letters due to its holonomic wheels. It generates complex compositions sometimes combining lines, letters and words. Its name refers to Isidore Isou the creator of Lettrism, a movement exploring the potential of letters, sounds, and signs.
This robot is also able to create figurative works. In this case an image is given and the robot tries to reproduce its silhouette.
ISU is the first to sign its artworks.
